Wrapping Coils / Toroids

[hkyle]

OK who here knows what to do?...I obviously don't.

Is there a formula out there for how many wraps, what size of wire for a certain amount of volts / amps you want to put into a coil to step things up?

I want to put in 26v and bump that to 130v so a ratio of 1:5.

How many wraps of wire do I need for the primary of my toroid?

hkyle,

Have a read up on the following two part transformer guide which includes info on toroids:

For calculating inductance and wire sizes, check this page:

Hope that helps.
